INITIAL START UP

1. Remove the top and front panels.

2. Open the water valve, and observe that the two

float reservoirs fill up with water and shut off.

3. Switch on the electrical power.

4. Open the hand valves (in the liquid lines).

5. Open the ball valves (in the suction lines).

6. Switch on one master switch, and observe:

The liquid line valve opens

The gearmotor runs

Within a short time, that side of the machine

begins to make ice.

Water flows from the water reservoir, and the float

drops, letting in more water.

7. Switch on the other master switch, observe that:

The liquid line valve opens

The gearmotor runs

Within a short time, that side of the machine

begins to make ice.

Water flows from the water reservoir, and the float

drops, letting in more water.

8. With both sides operating, the sight glass

should remain full, and the low side pressure will

be about 30 psig, + or - 2 psig. Gearmotor amp

draw should not exceed the nameplate rating.

9. Check the system very carefully for any

refrigerant leaks, repair as needed.

FME2400RH

COMPONENT IDENTIFICATION

Liquid line valve(s)

These valves operate to turn the ice making

process on and off.

When the ice level drops in the ice chute, the ice

level sensor will cause the circuit board to close

the liquid line relay, which energizes the liquid line

valve for that side of the system. The liquid line

valve opens, and liquid refrigerant flows to the

thermostatic expansion valve.

Thermostatic Expansion Valve

The metering device of each system, the valve(s)

sense the temperature of the suction line and vary

the amount of liquid refrigerant that passes

through the valve into the evaporator, thus

maintaining a constant level of refrigeration. TXV’s

are factory set. Do not adjust unnecessarily.

DO NOT ADJUST THE TXV UNTIL THE EPR

HAS BEEN SET.

The superheat setting is 4-8

F. Measure the

temperature of the evaporator outlet at the TXV

bulb, and check the low side pressure at the EPR

valve. Convert the pressure to temperature (using

a temperature pressure chart) and subtract the

amount from the outlet temperature. The result is

the superheat. Use an electronic thermometer.

EPR: Evaporator Pressure Regulator Valve

This valve maintains a constant pressure on its

inlet (evaporators) side regardless of the pressure

on the outlet (suction) side. The EPR is factory set,

adjust only if needed. After adjusting, re-check

TXV superheat.

Evaporators:

Where the water is frozen into ice crystals. As the

water cools, it begins to turn into ice, and the

slowly turning auger lifts the ice, as it is being

made, and forces it up and out of the “breaker” or

spout where the extra water is compressed out of

the ice. The ice then drops through the chute, into

the storage bin.

Auger: A solid stainless steel double spiral auger,

it pushes the ice crystals up to the top of the

evaporator.

Water Seal: A two part “face” seal, the top half

rotating with the auger, the bottom half stationary,

the sealing action being where the two seal “faces”

meet.

Ice Sweep: A plastic cap with “fingers”. It revolves

with the auger to “sweep” the ice into the ice chute.

Divider: Where the ice is compressed and much of

the extra water is squeezed out of it before it is

discharged into the bin.

Motor: A split phase motor that drives the gear

reducer.

Bearing: As the ice is pushed up the evaporator,

the auger is thrust down, and pressure from the

auger thrust is taken up by this bearing.

ELECTRICAL SEQUENCE

Refer the wiring diagram as needed.

Each system is separate

If the machine is switched off at the master switch,

but is otherwise ready to go, switching the master

switch to on does the following:

•The bin empty light on the circuit board goes on

•There is a 15 second delay

•If there is enough water in the reservoir, the

circuit board will allow the machine to start up.

Start up consists of:

•The liquid line relay and auger motor relay

become energized, connecting power to the

windings of the auger motor.

•The auger motor starts, and the centrifugal

switch closes, connecting power to the liquid

line valve coil.

•The liquid line valve opens, and the refrigerant

flows to the thermostatic expansion valve and

into the evaporator.

•As ice goes past the ice level sensors, the bin

empty light will stay on, and the machine will

continue to run, unless the ice stays between

the sensors for more than 15 seconds (bin full).

At that point, the bin empty light goes out, and

the machine shuts down.

Shut Down consists of:

•The liquid line relay opens.

•The liquid line valve closes

•Ice making stops

•The auger motor is run by the circuit board for 2

more minutes, clearing out ice in the

evaporator, and then

•The auger motor relay opens, and the auger

motor stops.

If the ice level sensor is clear (bin empty) for more

than 15 seconds, the machine will start up again.

Another purpose of the circuit board is to turn the

machine off if there is not enough water in the

machine.

•When the water level in the reservoir falls

below the water level sensor, the machine will

“shut down”

•When the water refills the reservoir, the

machine will start up again.

Separate from the circuit board:

•The master switch is the manual control for

each system, but it is not a service disconnect.

OPERATION

Water

Water enters the machine through the 3/8" male

flare at the rear of the cabinet, goes to the water

reservoir which it enters through the float valve.

The water then goes out the bottom of the

reservoir tank to the bottom of the evaporator.

Reservoir overflow or evaporator condensation is

routed to the drain.

OPERATION: Refrigeration

The remote high side

supplies high pressure

liquid refrigerant to the

liquid line connection on

the ice machine. After

the sight glass, there are

two separate liquid lines,

each leading to a liquid

line valve. When the

individual ice level

sensor causes the circuit

board to energize the

liquid line valve, the

valve opens, allowing

the liquid refrigerant to

enter that expansion

valve. The thermostatic

expansion valve meters

the liquid refrigerant into

the evaporator, where it

boils off (evaporates)

and absorbs heat. It

then moves through the

ball valve and into the

evaporator pressure

regulator valve, or EPR.

The EPR keeps the

evaporator pressure

above a predetermined

point, even though the

suction line pressure of

the remote high side

system may vary. The

refrigerant, now a low

pressure gas, moves

into the suction line of

the remote high side

system.

MAINTENANCE AND CLEANING

A Scotsman Ice System represents a sizable investment of time and money in any company’s business. In

order to receive the best return for that investment, it MUST receive periodic maintenance.

It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable, and

less costly in the long run, to avoid possible down time by keeping it clean; adjusting it as needed; and by

replacing worn parts before they can cause failure. The following is a list of recommended maintenance

that will help keep the machine running with a minimum of problems.

Maintenance and Cleaning should be scheduled at a minimum of twice per year.

ICEMAKING SYSTEM: In place cleaning

1. Check and clean any water treatment devices,

if any are installed.

2. Pull out and remove the front panel.

3. Move the ON-OFF switch to OFF.

4. Remove all the ice from the storage bin.

5. Remove the cover to the water reservoir and

block the float up.

6. Drain the water reservoir and freezer assembly

using the drain tube attached to the freezer water

inlet. Return the drain tube to its normal upright

position and replace the end cap.

7. Prepare the cleaning solution: Mix eight

ounces of Scotsman Ice Machine Cleaner with

three quarts of hot water. The water should be

between 90-115 degrees F.

8. Slowly pour the cleaning solution into the water

reservoir until it is full. Wait 15 minutes, then

switch the master switch to ON.

9. As the ice maker begins to use water from the

reservoir, continue to add more cleaning solution

to maintain a full reservoir.

10. After all of the cleaning solution has been

added to the reservoir, and the reservoir is nearly

empty, switch the master switch to OFF.

11. After draining the reservoir, as in step 6, wash

and rinse the water reservoir.

12. Go thru steps 13-19 to sanitize the ice machine

water system.

13. Mix two gallons of sanitizer solution. Use an

approved sanitizer.

A possible sanitizer solution may be obtained by

mixing two gallons of warm (90-115

F.) potable

water with 1 ounce of household bleach.

14. Slowly pout the sanitizer solution into the water

reservoir until the float rises, then switch the

master switch ON.

15. As the ice machine uses water from the

reservoir, continue to pour the sanitizer solution

into the reservoir.

16. After

⁄

of the sanitizer solution has been

added to the reservoir, and the reservoir is nearly

empty, switch the master switch OFF.

17. Drain the reservoir and thoroughly wash the

interior of the reservoir and cover with sanitizer

solution. Be sure the drain hose is upright and

capped.

18. Remove the block from the float in the water

reservoir.

19. Switch the master switch to ON

20. Continue ice making for at least 15 minutes, to

flush out any cleaning solution.

DO NOT USE any ice produced from the

cleaning solution. Be sure no ice remains in

the bin.

21. Remove all ice from the storage bin.

22. Add warm water to the ice storage bin and

thoroughly wash and rinse all surfaces within the

bin.

23. Sanitize the bin interior by washing the interior

of the bin with the balance of the sanitizer solution.

24. Switch the master switch ON.

These compounds may

cause burns.

If swallowed, DO NOT

induce vomiting. Give

large amounts of water or

milk. Call Physician

immediately. In case of

external contact, flush with

water.

Keep out of the reach of

children.

MAINTENANCE

1. The bin control uses devices that sense light,

therefore they must be kept clean enough so that

they can “see”. At least twice a year, remove the

bin control sensors from the base of the ice chute,

and wipe the inside clean, as illustrated.

2. The ice machine senses water level by a probe

located in the water reservoir. At least twice a

year, the probe should be removed from the

reservoir, and the tip wiped clean of mineral

build-up.

3. The bearing in the breaker should also be

checked at least two times per year.

Check the bearing by:

•pushing the bail clamp back and removing the

ice chute cover

•unscrewing the ice sweep

•unscrewing the breaker cover

•unscrewing the auger stud

Inspect the assembly, looking for wear.

See Removal and Replacement to replace bearing

or seals. Reverse to reassemble.

4. Check and tighten all bolts and screws.

CLEANING

In some installations the water supply to the ice

maker will be so concentrated with dissolved

minerals, (such as calcium carbonate) that as ice

is made, the evaporator and auger become

coated with the minerals, requiring a more frequent

cleaning than twice per year. If in doubt about the

condition of the evaporator and auger, the auger

can be removed so the parts can be inspected.

Note: Water filters can filter out suspended solids,

but not dissolved solids. “Soft” water may not be

the complete answer. Check with a water

treatment specialist regarding water treatment.

Switch off electrical power, and shut off the water

supply.

For more information on removal of these parts,

see REMOVAL AND REPLACEMENT.

1. To remove the auger, remove front and top

panel. If top panel cannot be removed, or if there is

less than 6" clearance over the top of the machine,

the gearmotor/evaporator may be slid out for

service access. See Removal And Replacement.

2. Push bail clamp back and remove ice chute

cover.

3. Unscrew and remove ice sweep.

4. Loosen band clamp under ice chute, and

remove ice chute from evaporator.

5. Remove 4 allen head screws holding breaker to

evaporator.

6. Pull up on breaker to remove auger.

Allow the auger to dry, the stainless steel of the

auger and evaporator must be clean and bright.

Clean the auger and evaporator as required. DO

NOT HONE THE EVAPORATOR.

7. Replace the water seal.

8. Reverse to reassemble.

SERVICE DIAGNOSIS: Condition - No Ice Being Produced

STATUS: NOTHING OPERATES

A. Check: Voltage to the unit, restore it if there is none. Compare to the nameplate.

B. Check: The master switch, switch ON if off.

C. Check the water level in the reservoir. The machine will not run if there is not enough water in the

reservoir. Restore/adjust water level.

STATUS: NOTHING OPERATES

D. Check: The gear motor, if it will not run, the liquid line valve will not open. If no power to it:

Check: The indicator lights on the circuit board, the bin empty light should be ON, the no water light should

be OFF .

1. If the bin empty and no water lights are off, check the transformer.

a. Transformer “load” side should have 12 to 15 volts. If not, check the “line” side. The line

side should have between 208-230 volts. If the line side has the correct voltage and the

load side does not, replace the transformer.

2. If the transformer is good, and the bin empty light is OFF, check the ice level sensors.

a. Remove sensors by sliding them sideways out of the ice chute. Visually inspect them,

clean if needed.

b. Look through the ice chute “eye” hole for something blocking the ice chute.

c. If the unit still does not run, replace the ice level sensors.

d. If the bin empty light is still OFF, check the circuit board. SEE LAST PAGE FOR TESTER

INFORMATION

3. If the transformer is fine, and the “no water” light is ON, check the water level sensor.

a. Check the water level in the reservoir, restore if low. If the water level is ok:

b. Remove the water level sensor from the reservoir and clean the tip if dirty.

CAUTION: THE TIP IS MADE OF GLASS

c. Replace the water level sensor. If the no water light is still on, check that the

“water sen” plug is firmly plugged into the circuit board.

d. If the no water light is still on, SEE LAST PAGE FOR TESTER INFORMATION

e. If after the above, the machine still will not run, replace the water level sensor

STATUS: GEARMOTOR OPERATES, BUT NO ICE IS MADE

A. Check the liquid line valve relay.

The relay is on the circuit board, if it does not supply power to the liquid line valve, the

valve will not open.

1. Check for power at the valve coil, if none:

a. Check for power at the liquid line valve relay at the circuit board.

If there is power at the relay, but none at the liquid line valve coil,

Check for an open wire between the relay and the valve.

2. Check the valve coil. If the coil is open, replace the liquid line valve.

3. Check the auger drive motor centrifugal switch. If, when the drive motor is running,

contact 4 (black wire removed) has no power, and all of the above switches have been

checked, replace the centrifugal switch, or the drive motor.

4. If the liquid line valve relay on the circuit board has power on the NO contact, but not on the COM

contact, replace the circuit board.

To Remove the Auger:

Turn off the water to the machine, and unclip the

evaporator drain hose, pull it down and drain the

evaporator into the bin or a container.

1. The top panel must be removed.

2. Remove ice chute cover.

3. Unscrew ice sweep.

4. Loosen band clamp and remove ice chute body.

5. The auger and breaker/bearing may now be

removed as an assembly.

a. Unscrew 4 allen head cap screws holding

breaker to evaporator.

b. Lift up on breaker and remove auger from

evaporator.

Note: If the auger is stuck, the breaker must be

removed from the auger.

The breaker may be removed from the auger and

evaporator without disturbing the auger.

a. Use spanner wrench and unscrew breaker

cover from breaker (left hand threads)

b. Unscrew auger stud from top of auger.

c. Unscrew 4 allen head cap screws holding

breaker to evaporator.

d. Lift up and remove breaker from evaporator.

e. If the auger is stuck use a slide hammer type

puller to pull on the auger at the threaded hole.

The size of that hole is 5/8"-18.

Inspect the auger, the critical areas of the auger

are:

1. The auger body. It should be clean and

shining. Sometimes an auger will appear clean

when wet, but after it is dry it will be seen to be

stained. Scrub the auger with ice machine cleaner

and hot water.

Ice machine cleaner is an acid. Handle it with

extreme care, keep out of the reach of children.

2. The water seal area. Because the auger has

been removed, the water seal will have to be

replaced. Remove the water seal top half from the

auger, and inspect the auger for minerals clean as

required.
